HDTV is more popular for its sharper image, but other than the picture quality, what makes watching an HDTV a memorable experience is the Dolby digital sound. However, not all HDTVs come with a built-in sound system. If your HDTV does not have a built-in audio system, you need to connect an independent, external sound system to enhance the viewing pleasure. Unlike the stereo-sound of old televisions, HDTV offers enhanced realism in sound with full frequency response, low noise and exceptional clarity. If you want the full benefits of HDTV, make sure your system has Dolby digital 5.1. Look for the Dolby Surround Sound logo to avoid any confusion.

What is Dolby Digital 5.1 Surround Sound
Dolby Digital 5.1 Surround Sound is a discrete multi-channel digital audio format, and is the official audio standard for HDTV. Dolby Digital 5.1 Surround Sound is different from other Dolby systems. It delivers a separate channel to the Surround-Left and Surround-Right speakers. It also features a Low Frequency Effects channel to drive the subwoofer, which provides the bass.

How does Dolby Digital 5.1 Work
• The left, center and right channels are located in front of you, and provide precise, clear positioning of dialogue.
• The Surround-Left and Surround-Right speakers are located behind you to deliver ambient sounds.
• The subwoofer or effects channel sends an explosive punch during action sequences.

How to Connect and Set Up
You just have to make a single-cable digital connection to your A/V receiver to receive the crystal-clear Dolby Digital sound. If you want to harness the full power of Dolby Digital 5.1 Surround Sound and maximize your HDTV experience, you must have a dedicated audio system comprising at least five speakers, plus a subwoofer for extreme low frequencies, and of course, ample power to drive them all. Place all the speakers at recommended locations to enjoy the optimal surround sound experience from your HDTV.

The Advantages of Dolby Digital 5.1
If you are watching a movie, you can enjoy the full-scale auditory experience that its creators intended, and hear everything from the roar of the crowds to the panting of the athletes when watching live sporting events such as auto racing, football, basketball, baseball, hockey, and soccer. By combining HDTV's wide screen pictures, ultimate clarity, and Dolby Digital 5.1, you get a truly impressive TV viewing experience.
